The invention discloses a pressure release valve control method and system, a vehicle and a medium, the current oil tank state and state control information are obtained, the current oil tank state is adjusted according to the state control information, and the oil tank working state is obtained; a pressure release valve is controlled to be opened or closed according to the working state of the oil tank, multiple working states are set for the high-pressure oil tank, and different high-pressure oil tank pressure release valve management strategies are set for each working state. The current oil tank state is adjusted according to the state control information, and the pressure, the oil tank liquid level and the carbon tank concentration are comprehensively considered to control the pressure release valve, so that the pressure of the high-pressure oil tank is maintained within a reasonable range. Therefore, the effect of flexibly controlling opening and closing of the pressure release valve is achieved, and the problem of saturation overflow risk of the carbon tank is solved.

    本申请公开了一种泄压阀控制方法、系统、车辆及介质,通过获取当前油箱状态和状态控制信息,根据所述状态控制信息调整所述当前油箱状态,得到油箱工作状态;根据所述油箱工作状态控制泄压阀开启或关闭,针对高压油箱设置多个工作状态,针对每种工作状态设置不同的高压油箱泄压阀管理策略。根据状态控制信息调整当前油箱状态,综合考虑压力、油箱液位和碳罐浓度对泄压阀进行控制从而使得高压油箱压力维持在合理范围。由此,达到了灵活控制泄压阀开闭的效果,解决了碳罐饱和外溢风险问题。
